(Cl. 12S-332) 4 Claims.

My present invention relates t-o a mechanism for applying rings to hogs noses. Among the objects of this invention are the provision of an apparatus for the purpose indicated which is automatic in its ring-closing action; the provision of an apparatus for the purpose indicated which has adjustable means for limiting the ringclosing action so that the ring can be closed to the necessary extent but cannot be closed so that the points project and therefore keep the hogs nose sore; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings and, while I have shown therein what is now regarded as the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not to be interpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof,

Fig. 1 shows a side elevation of a structure in accordance with my present invention, after it has been used and the closed ring has been withdrawn from between the ring-closing jaws; and

Fig. 2 shows this structure after the hammer has been drawn back and a ring inserted between the ring-closing jaws.

Reference will now be made in greater detail to the annexed drawings for a more complete description of this invention. This mechanism comprises a body I, a barrel 2, a hammer 3 sliding within the barrel and controlled by a compressible coiled spring 4 located partly in the barrel 2 and partly in an extension 5 thereof. The hammer 3 is provided with a cooking handle 6 by means of which the hammer may be drawn back, placing the spring 4 under compression. When the hammer 3 is Vdrawn clear back and turned slightly, the handle 6 is put into the notch 1 formed in the side wall of the barrel 2, the handle being held in the notch 'I until it is released by the action of the trigger 8 which is provided with a cam or eccentric surface 9 which engages the handle I5 and pushes it up until it is released from the notch 1. The trigger 8 turns about the pivot I0 as the link I I is shoved backwardly by engagement of the arm I 2 with the nose of the hog, when the operator is in the act of applying a ring to the hogs nose.

From .the forward end of the barrel 2, extends an arm I3 which has a box I4 at'its lower end, in which are mounted two jaws, a fixed jaw I5 and a movable jaw I5. The xed jaw I5 is held in place by a pin I1 which passes transversely through the box I4 and the jaw I5. An adjusting screw It passes through the Wall of the box -Ili and through the jaw I5, as shown clearly in the gures of the drawings. The inner end of the screw IS acts as a stop to limit the pivotal motion of the jaw I6, and the stopping point may be adjusted by loosening the nut I9, turning the screw IS in or out, and then again tightening the nut i9. In this way it is possible to limit the amount which the ring may be closed, which is advisable in order to prevent too much overlap of the ends of the ring, which would tend to make the hogs nose sore because of unnecessary iriction between the ends of the ring and the tissues of the hogs nose. This may be used for adjusting the closing of different sizes of rings, because such may vary with diierent manufacturers, as well as rings intentionally made of different sizes, of which there are, normally, three in number.

The jaw IIS has an upwardly extending arm 20 which reaches across the path of the hammer 3 so that when the handle 6 is released from the notch 1, the hammer 3 will strike the arm 20, as is clear from the drawings, which causes closing of the jaws I5 and I6 to the extent required for the closing of the ring 2 I. The jaw I6 is pivoted on the pin y22 which extends transversely through the box I4. A means 23 is provided for holding one end of spring 24, the second end of which is attached to the pivoted jaw I6.

An apertured ear 24a projects laterally from the box I4 and the link II slides freely through the aperture in that ear, the link being guided thereby. Toward its second end, the link passes through a securing means 25, the position of,

which with relation to the link is adjustable so that the arm I 2 will be properly positioned to result in the handle 6 being released from the notch 'I at a time to insure that the ring 2| will be properly applied to the hogs nose.

It is of course understood that the specific description of structure set forth above may be departed from without departing from the spirit of this invention as disclosed herein and as defined by the appended claims.

Having now described my invention, I claim:

1. A hog ringer mechanism comprising a pistol-shaped body having a forwardly extending barrel in which a hammer is longitudinally slidable, a compressible spring in said barrel and body, a handle for drawing said hammer backwardly into striking position, said hammer being urged forwardly by said spring, an arm extending downwardly from the forward end of said barrel and carrying at its lower end a box, a pair of jaws extending forwardly from said box, one of them being pivotally carried by the box and having an arm extending upwardly in front of the hammer, said arm being capable of being moved backwardly to raise the pivoted jaw so that a hog ring can be inserted between the jaws, the ringer barrel having a notch therein for the reception of the hammer handle, a pivoted release means for releasing said handle from said notch, and a link connected to said pivoted release means, extending forwardly to a position in proximity to the forward end of the jaws so that, when the forward end of the link is pushed against the hogs nose, the hammer will be released to cause closing of the ring.

2. A hog ringer mechanism comprising a body part having along one edge thereof a hollow barrel in'which is housed a compression spring and a 1forwardly slidable hammer, said barrel having in one side thereof a longitudinally extending sl'ot, at one end of which is a transversely extend ing notch, a handle connected to said hammer and extending through said slot, said handle being movable out of line of the slot and into the notch to hold the spring compressed, a lever pivotally mounted on the body in a position to engage the hammer handle and move it out of the notch into line with the slot, when the lever is turned about its pivot, whereby to release the ham-mer for longitudinal motion in the barrel, enabling the compressed spring to cause the hammer to move forwardly at a rapid rate, a pair of jaws connected to the forward end portion of the barrel, said jaws being adapted to receive between them a hog ring to be closed in the muscular part of a hogs nose when the ringer operates, one of the jaws being pivotally mounted and having an arm extending into the path of motion of the hammer, a trigger on the body, and a trigger operating link mounted on the side of the box and trigger and extending forwardly to engage the hogs nose to cause release of the hammer mechanism to cause closure of the ring.

3. A structure for the purpose indicated comprising a barrel having a slot extending longitudinally thereof in the intermediate portion of the barrel and a notch extending transversely of said slot at one end thereof and furnishing a means for holding a hammer in retracted position, a spring-pressed hammer slidable in said barrel, said hammer being extensible beyond the end of the barrel, a handle connected to said hammer, extending through said slot and capable of being moved longitudinally thereof to draw the hammer into the barrel, a supporting arm extending transversely of the barrel adjacent the forward end thereof and supporting a fixedjaw and a pivoted jaw to grip and closea ring, `spring means for moving the pivoted jaw around itspivotal connection to the arm and hold .it inV gripping engagement with a ring, a pivoted` trigger for releasing said handle from said transversely extending notch, and trigger-actuating means connected to the trigger and extending to a position adjacent the forward end of the jaws.

4. A structure as. defined by claim 3 in combination with adjustable stop means for 4limiting the pivotal motion of said pivoted jaw about its.

pivot, whereby to adjust the extent to which a` ring may be closed.
